A page from a 13th century music manuscript (the "Wilton processional")whose pages were broken up ca. 1948 by Otto Ege; this page is now in New Zealand: https://www.flickr.com/photos/dplmedmss/8647514892/. An inventory of the leaves is here: https://cantusdatabase.org/source/620437. The page has nine sets of red staff lines, and the same Latin text beginning "Nunc sancte nobis..." is written three times. There appear to be ghostly notes on some of the staves, but no legible musical notation.
the layout of this #chant page makes it look like the scribe was just made to copy out "nunc sancte nobis" indefinitely like some medieval Bart Simpson #fragmentfriday
